Battery is HOT

Just got done charging a 7 cell 3000mah 8.4volt nimh and I just checked it was done but as usual I see how hot it is and I can't keep it in my hand for more than 4-5 seconds without it burning. The sad thing is it came at Christmas a MAX of 15-20 uses. Thanks for looking

We both have a stampede xl-5 I know it gets hot but this is EXTREME compared to normal, we have the standard Ez-peak charger normally it is warm and I can hold it but this is hold it like a hot potato I can't for a time more than 5 (still starching the max) seconds

I have the same question.
I use a b6pro ac computer charger to my new 3000mh 8,4v battery from traxxas and i have it on 3 amp when i charge.
Charged it for the first time on 3a that give it 1c charge, it been real hot, the temprature was 55c when it was finish. Is this normal or could it been damaged?

With my 6 cell and 7 cell 5000 m-h NiMHs, venom and traxxas, they stay at ambient during the majority of charging using Onyx 235, Traxxas wall plug charger, and Dynamite Wall chargers. These are all peak chargers. Using the Onyx I will charge anywhere from 0.1C to 1C.

With 2 minutes left to charge and for a couple minutes after hitting peak, battery temps will rise anywhere from 113f to 135F. If I don't want the battery to heat up, I set a time limit or stop charging just before it tries to get to max charge. The problem seems to be in trying to get to that last bit of charge into the batteries to get to max.

If I know how many mAh I need to get in or I know the peak voltage I want to get to without overheating the battery, I'll set the charger to stop at a time point before achieving max charge ... No more overheating.

Having said that I've accidentally got my NiMH to 212F after 10 minute run in UL-1 hydroplane. Batteries still charge fine and run fine. Very lucky I guess, but in general it's best to keep NiMH and LiPo <143 degrees max.
